Large-volume paracentesis can trigger hemoperitoneum from ruptured mesenteric varices, a serious complication of portal hypertension. Prompt diagnosis and intervention are crucial for managing this rare but life-threatening condition.

Area of Science:

  • Gastroenterology
  • Hepatology
  • Interventional Radiology

Background:

  • Portal hypertension frequently leads to ascites, often managed with large-volume paracentesis.
  • Mesenteric varices are a known complication of portal hypertension, carrying a risk of bleeding.

Observation:

  • Acute hemoperitoneum developed in four patients (48-68 years) with refractory ascites following large-volume paracentesis (> 4000 mL).
  • Symptoms included abdominal pain and hemorrhagic shock, occurring 3 hours to 4 days post-procedure.
  • Mesenteric venous retrograde flow, indicative of collateralization, was observed via duplex sonography in three patients prior to bleeding.

Findings:

  • A causal relationship between large-volume paracentesis and hemoperitoneum from mesenteric variceal rupture is suggested.

  • The proposed mechanism involves a sudden decrease in intraperitoneal pressure, increasing stress on mesenteric varices and leading to rupture.
  • Mortality can be as high as 70% in cases of hemoperitoneum from mesenteric variceal rupture.

    • Implications:

    • Awareness of this complication can expedite diagnosis and treatment of hemoperitoneum post-paracentesis.
    • Treatment strategies include surgical ligation, transjugular intrahepatic portosystemic shunt (TIPS), and embolization.
    • Early recognition and intervention are critical for improving patient outcomes in this high-mortality scenario.
